There's a weird cult-like attitude around 40fps that I've noticed. Personally I run everything at the normal 60hz and almost everything I play runs fine, even at the higher resolution (1920x1200) of my external monitor. Counter-Strike 2 runs horribly and Baldur's Gate 3 was sub-60, but mostly I don't play anything that demanding (mostly indie, lots of 2D). It might matter more if you play all the new AAA titles that come out.
